How can I install OpenBSD on this device?

- Installed rEFIt on MacOS X to get a boot selector
- dd'ed install53.iso to USB-Stick (sd0c) using another OBSD machine

Then simply choose MBR instead of HFS and for customized install remove all existing partitions -if any- except i as it is needed then add new partitions the way you wish
on reboot go to openfirmware and type :

Code:

setenv boot-device hd:,ofwboot /bsd
reset-all

So that you can autoboot the bsd kernel.
That has always been my case (ie. whole disk , iBook/iMac)

I've got a nice new MacBook Air and while I'm not planning on uninstalling OS X anytime soon, I will certainly put OpenBSD on an Apple Laptop. The idea of it just sounds so cool. Thanks for the thread!
